change-case-all

What is change-case-all?

The change-case-all npm package is a utility library that provides a comprehensive set of functions for transforming the case of strings. It includes functionalities for converting strings to camel case, capital case, constant case, dot case, header case, no case, param case, pascal case, path case, sentence case, snake case, and swap case. This makes it a versatile tool for formatting strings in various coding and writing styles.

What are change-case-all's main functionalities?

Camel Case

Converts a string to camel case, which is a common case style in programming where the first letter of each word is capitalized except for the first word.

"use strict"; const { camelCase } = require('change-case-all'); console.log(camelCase('test string')); // 'testString'

Constant Case

Transforms a string to constant case, typically used for defining constants in programming, where all letters are uppercase and spaces are replaced by underscores.

"use strict"; const { constantCase } = require('change-case-all'); console.log(constantCase('test string')); // 'TEST_STRING'

Pascal Case

Converts a string to pascal case, similar to camel case but with the first letter of the first word also capitalized. Commonly used for class names in programming.

"use strict"; const { pascalCase } = require('change-case-all'); console.log(pascalCase('test string')); // 'TestString'

Snake Case

Transforms a string to snake case, where all letters are lowercase and spaces are replaced by underscores. Widely used in programming, especially in variable naming.

"use strict"; const { snakeCase } = require('change-case-all'); console.log(snakeCase('test string')); // 'test_string'

Other packages similar to change-case-all

lodash

Lodash is a comprehensive utility library that, among its wide range of functions, includes methods for changing the case of strings (e.g., _.camelCase, _.snakeCase). While lodash offers similar string case conversion functionalities, it is a much larger library aimed at providing a broad spectrum of utility functions beyond string case conversion.

case

The 'case' package is another npm library focused on string case conversion. It supports various case transformations similar to change-case-all. However, change-case-all provides a more extensive set of case conversion utilities, making it a more versatile choice for projects that require diverse string manipulation capabilities.

README

change-case-all

Change case functions for all cases in TypeScript and JavaScript. Combined version of all change-case methods, so you do not need to install them separately. ESM and CJS bundles are included, also backwards compatible with change-case@4.1.0.

change-case-all@2.0.0 introduces a Case helper class, which can be used to access all methods.

Usage

npm install --save change-case-all

Browser / ESM

import { Case } from 'change-case-all';
const camel = Case.camel('test string'); // testString
const upper = Case.upper('test string'); // TEST STRING


import { camelCase, upperCase, ... } from 'change-case-all';
const camel = camelCase('test string'); // testString
const upper = upperCase('test string'); // TEST STRING

Node.js

const { Case } = require('change-case-all');
const camel = Case.camel('foo-bar'); // fooBar
const snake = Case.snake('fooBar'); // foo_bar

const { camelCase, snakeCase } = require('change-case-all');
const camel = camelCase('foo-bar'); // fooBar
const snake = snakeCase('fooBar'); // foo_bar

Changelog

2.1.0

• Bundle dependencies in module to support Node.js

2.0.0

• Updated dependencies to change-case@5.2.0
• ParamCase → now KebabCase
• HeaderCase → now TrainCase
• Create mjs and cjs bundles
• Introduce Case helper class: e.g. Case.camel('test string'); // testString
• TitleCase@4.1.0 failing in tests, thus kept at 3.0.3
